101,112,131,415,161, next number in sequence
2 answers:
This actually a puzzle, not a math problem.
Write it out with no commas:
101112131415161
it actually says 10, 11, 12, etc.
so the next number would be 718
This is just a random thing your teacher assigned. The next number is 718

Answer: 5
5 + 2(4 x 2 - (2 +2))
5 + 2(8 - 2(2 + 2))
5 + 2( 8 - 8)
5 + (2)(0)
5 + 0
=5
he is seven because you divide alans age 14 by two equals 7
